Be it known that we, DANIEL Huus'r and I-lcnunur Krxasrox Bn'mcrm, subjects of the King of Great Britain and Ireland, residing at Cumhria, Marlborough Road, Chiswiek, London, \V. and 57 Moor-gate street, London, E. C, England respectively; have invented certain new and useful Improvements in Bottles, Jars, and the Like and in Stoppers Therefor. of which the. following is a specification.

This invention for improvements in hottle, jar and like stoppers has for its object a simple and etlicient elasticair-tight. packing for bottle stoppers and the like requiring only a small amount of the elastic, packing and that shall readily allow of the bottle being exhausted and relates to stoppers or pluugers in' which an elastic ring ts tight between the bottle and the stopper or pluner and is free to roll or slide up the plun i261 and down the hottle nec 55 the Stopper or plunger is applied and according to this invention the stopper or plunger is provided with a recess or passage leading to the bottom of the stopper or plunger andopens out on the cylindrical surface of the stopperor plunger just above the elastic ring when in its lowermost position.

This invention also consists in providing means for releasing the vacuum.

Referring to the accompanying drawings, Figure l is a sectional view of a hottle neck and stopper therefor with means for facilitating the exhausting of the bottle, Fig. 2 is a plan of same, Fig. 3 is a sectional elevation of a hottle neck and stopper therefor showing a means for releasing the vacuum, Fig. l shows the stopper as a cap fitting over the hottle neck;

in the aplilieation of our invention to a hottle stopper, the rubber ring a of ciwular section is placed around the stopper 7/ at its lower end. In order to facilitate the exhausting of the hottle, small inclined grooves mare cut in the lower edge of the stopper (Figs. 1 and or in the upper edge of the hottle neck when a cap is used, as in Fig. l where the cap is shown bedding down on a flange 1/. The stopper is made of such a diameter that. when inserted in the hottle neck 0 the ring a is compressed as shown. thus insuring a tight joint. \Vhen the stopper is inserted a little way there is free access of air through the slots-m and over the top of the ring a and the bottle can he PATENT OFFICE.

The stopper may be corrugated s li ow and may have a fiange'e toprevent thering .I from coming'otf With a flangelessstopperg or with the cap, the vacuum may'he easily releasedhy inserting a pointer Ia between the ring and one of the surfaces, and in the case of the flanged stopper, :1 slot 1 may be formed in the flange to allow of the insertion of the pointer is as shown in Fig. 1. A"sq'nare section ring may be used. \Vith this shape ring, there is a lock at every 'quarter turn of the. ring, so that' the stopper may he made much shorter. Vhere it 15 desired to use a fiangelessstopper'for bottles or jars under pressure in order to paste a. paper seal over the mouth of the stopper, means. must be provided for holding'the stopper in position and preventing it from I being forced out by the pressure.

That we claim and desire to secure by 96 Letters Patent is 1. The combination with a bottle neck having a uniform engaging. surface and a stopper therefor having channels or grooves extending along its base near the lower end 9: thereof and the remainder of said stopper having a. uniform ei'igagingtsurface, and a ring of rnhhcr adapted to he interposed hetwccn the grooved portion of the stopper and the neck of the hottle and moved he- 1 tween the uniform engaging surfaces of the neck and stopper and downwardly with respcctlo the. neck and upwardly with respect to the stopper upon insertion thereof into the neck and to a final point above 1 said groove.

2. The combination with a bottle neck havinga uniform engaging surface anda stopper therefor having channels or grooves extending along its lower base from the 1 lower. end upwardly and also haying portions projecting outwardly near the, lower the neck and stopper and with respect to endthereofytheremainder of said stop er having a uniform engaging surface, an a ring of'rubber adapted to be inte" osed be tween the. grooved portion of th stopper above its projecting portions, 'andthe neck ofmthebottle, said ring moving downwardly betweenthe uniform engaging surfaces of the neck and upwardly with respect to the stopper upon insertion thereof'into the neck an to a point above such grooved or chan neled portion.

3. The combination with a bottle neck havinga uniform engaging surface and a stop'per. therefor having channels or grooves extending from its lower end upwardly a slight distance therefrom, the remainder "of said stopper having a uniform engaging surface, said stopper'having circumferens.

tially disposed grooves near the lower end thereof and intersecting said first named grooves, and a ring of rubber adapted to be interposed between the grooved portion of the stopper and the neck and moved tween t e closure member, there downwardly with respect to the neck and 5 manner to be shifted beyond said grooves when the closure is' forced Into aclosing position. In testimony whereof we have 'pflixed our signatures, in presence of two w tnesses.- 111mm mmsr. HERBERT KYNASTQN BRIDQEB. Witnesses: i
